World's most accurate clock unveiled

The most precise experimental atomic clock has been developed in the United States that neither loses nor gains a second in five billion years.      


According to Press TV, the newly created experimental strontium clock has set new world records for both precision and stability, the researchers claim.

The finding was achieved by a team of researchers from the National Institute of Standards and Technology (NIST) in Boulder, United States.

The clock includes a few thousand atoms of strontium kept in a column of about 100 pancake-shaped traps called an optical lattice formed by intense laser light.

“Scientists detect the strontium atoms' ticks (430 trillion per second) by bathing the atoms in very stable red laser light at the exact frequency that prompts the atoms to switch or tick, between energy levels."

The clock is placed in a laboratory at the Joint Institute for Laboratory Astrophysics, operated by the NIST and the University of Colorado Boulder on the university's campus.
